General Description
1-2
C141-E133-02EN
1.1
Standard Features
(1)
Compactness
In a compact enclosure having the 3.5-inch HDD form factor, the IDD contains an FC-AL controller,
which supports the Arbitrated Loop technology (FC-AL), a Fibre Channel technology defined by the
related ANSI standard.
(2)
FC-AL standard
The IDD provides not only FC-AL basic functions but also the following features:
•
Arbitration
•
Disconnection/Reconnection
•
Data bus parity
•
Command set which meets the logical specification of the SCSI CCS (Common Command Set
for Direct Access Device) requirements (Rev. 4.B)
The SCSI commands can manipulate data through logical block addressing regardless of the physical
characteristics of the disk drive. This allows software to accommodate future expansion of system
functions.
(3)
Dual-port support
The IDD has two pairs of driver and receiver sets for the Fibre Channel to support dual-port
connection.
(4)
High-speed data transfer
The maximum data-transfer speed on the Fibre Channel loop is 212.5 MB/s. The large-capacity data
buffer of the IDD enables the effective use of such high-speed data transfers available on the Fibre
Channel loop.
(5)
Continuous block processing
The addressing method of data blocks is logical block address. The initiator can access data by
specifying block number in a logically continuous data space without concerning the physical
structure of the track or cylinder boundaries.
The continuous processing up to [64K-1] blocks in a command can be achieved, and IDD can perform
continuous read/write operation when processing data blocks on several tracks or cylinder.
